Greetings:

Not sure if anyone mentioned this: Have you checked each mixer channel 
for noise ? I've found that the CD channel and another channel (AC97?) 
on my SBLive mixer produce an incredible amount of noise that disappears 
entirely when those channels are muted. I don't know what channels you 
have available on your audio chipset's mixer, but you should check each 
one for noise.

CD channels seem to always produce much noise, probably due to the cheap 
drives I buy.

Best,
